“…Apart from these Magnesium alloys are having lower maintenance and production costs [7]. However, the Magnesium alloys have relatively low young's modulus, but this can be mitigated by using stiffer and harder ceramic particles as reinforcements [8]. The Magnesium hybrid metal matrix composites are produced by using various methods such as stir casting, powder metallurgy, squeeze casting and friction stir processing.…”

Composite materials are being widely studied for the last few decades, and it has optimized the day to day applications in the engineering field. In this advancement, the use and development of metal matrices was a significant outcome that concentrated on the addition of many particulate materials in a metal matrix at nano and micro levels. Among these Magnesium, metal matrices are having a high potential, especially in transport, defense, and aircraft industries. Many research works are being carried out to use the capabilities of Magnesium and has provided excellent results. This paper is an overview of the development, processing, and improvement of properties in Magnesium alloys. Various manufacturing processes such as self-propagating high-temperature method, stir casting, laser cladding, and powder metallurgy has been used to develop the magnesium composites for increasing the properties by using various wt% of reinforcements added in the matrix. The improvement in mechanical properties such as tensile strength, yield strength, hardness and tribological properties such as wear rate is reviewed. The different properties and capabilities of Magnesium alloys such as AZ31, AZ91, and ZE41 is also discussed from the various research works.

“…Their excellent mechanical properties are attributed to (1) an external force load transfer between the matrix and the reinforcement, (2) dislocation strengthening, (3) re ned grain strengthening, (4) precipitation hardening, (5) solid solution strengthening, (6) mixed strengthening, and (7) synergistic strengthening [5]. The four types of methods generally used to manufacture PMMCs are stir casting [6][7][8][9], pressure penetration [10], powder metallurgy [11][12][13][14], and mechanical alloying [10]. Although stir casting is a low-cost method that has been employed worldwide [2], powder metallurgy can avoid the following unwanted phenomenon, namely: (i) agglomeration of the ceramic particles during mechanical agitation, (ii) settling of the ceramic particulates, (iii) segregation of the secondary phases in the metal matrix, (iv) extensive interfacial reactions, and (v) ceramic particulate fracture during mechanical agitation [15].…”

“…Ceramic particles such as SiC, BN, TiC, TiB 2 , TiN, ZrO 2 , ZrN, MoC, WC, and Al 2 O 3 are commonly used as metal matrix composite reinforcements [3,10,16]. However, ceramic powders with diameters of less than 50 µm (d 50 < 50 µm) are cohesive because of the large interparticle force (electrostatic, Van der Waal's, and liquid bridge forces) [17].…”

In this study, powder metallurgy was used to fabricate titanium nitride/nickel metal-matrix composites. First, Ti and Ni powders with weight ratios of 20:80, 50:50, and 80:20 were dry mixed for 24 h. After cold isostatic pressing, the green compacts were soaked in a water-based hot forging lubricant and sintered at 850, 950, and 1050°C for 1.5 h in an air atmosphere. The effects of the amount of titanium powder and the sintering temperature on the mechanical properties (hardness, wear resistance, and compressive strength) of the composites were investigated. The results indicated that titanium gradually transformed into titanium nitride near the surface after sintering due to the carbothermal reduction reaction; this transformation was observed to significantly increase the hardness. In addition, a titanium oxide film was observed to form between the titanium particles and the nickel matrix. The optimum sintering temperature of 950°C provides the composites with titanium-nickel weight ratios of 20:80 and 50:50, the latter of which exhibited the best mechanical properties (wear resistance and compressive strength). Furthermore, increasing the titanium content to 80% in the composite increased the hardness; however, the wear resistance and compressive strength were observed to reduce.

The results indicated that titanium gradually transformed into titanium nitride near the surface after sintering due to the carbothermal reduction reaction; this transformation was observed to significantly increase the hardness. In addition, an oxygen-rich film was observed to form between the titanium nitride particles and the nickel matrix. An optimum sintering temperature of 950 °C provides the composites (titanium–nickel weight ratios of 20:80) the best mechanical properties (wear resistance and compressive strength) among other groups. Furthermore, increasing the titanium content to 80% in the composite increased the hardness; however, the wear resistance and compressive strength decreased.
